Pharmacodynamic responses of exogenous epinephrine during mandibular third molar surgery.

Background: The systemic effects attributable to the injection of dental local anesthetic solutions have been the subject of discussion for many years.

Aim And Objective: The aim of the present study was to investigate the biochemical and hemodynamic effects of adrenaline in lignocaine local anesthetic solutions when used in clinical doses in patients undergoing third molar surgery under general anesthesia.

Materials And Methods: Of the total 30 patients, 15 were given local anesthetic solution containing adrenaline and the other 15 were given the same without adrenaline.

Carnoy's solution in the mangement of odontogenic keratocyst.

Carnoy's solution is a substance used as a complementary treatment after the conservative excision of odontogenic keratocyst. The application of Carnoy's solution promotes a superficial chemical necrosis and is intended to reduce recurrence rates. However, the inferior alveolar vascular-nervous plexus can occasionally be exposed after the removal of a lesion.

Appraisal of the cephalometric norms for the upper and lower lips of the South Indian ethnic population.

Aim: The guidelines for planning an improvement in the facial appearance till recently existed in the form of evaluation of linear and angular parameters and ratios related to the hard tissues in the various cephalometric analyses. The present study aimed at establishing Arnett et al.'s norms of the upper and lower lip for the local population and assessing the extent by which these differ from the original norms proposed by Arnett et al.
